I have had the MS shocks and springs for the years .... It's a great setup for the road but not a huge improvement over stock on the track . I can't speak from experience but from what i hear the ohlins would make a night and day difference.

I'm currently running stock springs with MS shocks. I'm thinking either about getting the MS springs and MS Front Tower Bar to improve the car for track.

How will those upgrades compare to just upgrading to Ohlins DFV coilovers?

Should I go direct to Ohlins or can I still find the same enjoyment from the MS setup?

All in all, I think I'm just trying to get the life out of the MS shocks with the MS springs... but not sure how much improvement I will really see adding the springs.

Let me know your thoughts on what might be best.

Thanks,

Go direct to Ohlins.
MS springs, if you can find them, are like a 15% stiffness improvement over stock. Barely noticeable.
Ohlins or any other serious coilover are ~5x stiffer than stock. Don't worry, they're still comfortable.
MS front strut tower bar is a waste of money.
Incremental upgrades in general are a waste of money, go straight for the best.
